Used in the field. Here, the male member is a belt-shaped base portion that is welded to the inner surface of the bag near the opening by heat sealing or the like, and a cross-section protruding from the belt-shaped base portion and having a swelling tip, along the extending direction of the belt-shaped base portion. And a male occlusal portion that extends.

Similarly, the female member is composed of a strip-shaped base portion and a female bite portion having a curved cross-section that meshes with the tip bulge portion of the male occlusion portion and extending along the extending direction of the strip-shaped base portion. It The bag having the above-described articulating device also has the same problem as described above.

The object of the present invention is to prevent the misuse of the atmosphere-improving substance and the leakage of the input, and to freely select the packaging material.

There is no need to consider the combination of the atmosphere improving substance and the packaging material, because the atmosphere improving tape for packaging can be separately fixed to the packaging material such as a sheet and used without adding the atmosphere improving substance to the packaging material. Therefore, the packaging material of the packaging body such as the packaging bag can be freely selected. Further, since the atmosphere improving substance is contained only in the tape portion, it is possible to reduce the loss at the time of manufacturing the package, so that there is no environmental load. Further, since the atmosphere improving layer has a cross section coated with the thermoplastic resin layer, the atmosphere improving substance does not leak out from the atmosphere improving tape for a package, so that the product in the package is contaminated. Nothing.

The atmosphere improving tape for a package of the present invention comprises:
An atmosphere improving layer containing an atmosphere improving substance and a thermoplastic resin layer not containing the atmosphere improving substance are provided, and the atmosphere improving layer has a cross section laminated on the thermoplastic resin layer.

Here, the cross-sectional form of the atmosphere-improving tape for a package may be any form as long as the atmosphere-improving layer has a cross-section laminated on the thermoplastic resin layer.

According to the present invention as described above, the atmosphere-improving tape for a package is continuously heat-bonded to the inner surface of the sheet when the package with the atmosphere-improving tape is formed. As compared with the case where the sheet itself having the atmosphere improving layer is manufactured as a package, since the atmosphere improving tape for a package is only heat-bonded in the package, there is no waste and the cost is low. The atmosphere improving performance can be easily imparted to the package. In addition, since the atmosphere improving tape for packaging is heat-bonded to the sheet, compared with the case where it is pasted with an adhesive or a pressure-sensitive adhesive,

Suitable for multiple uses. Further, since it is only necessary to attach the articulation device without attaching the atmosphere improving tape for the package separately, the manufacturing is easy.

In the engaging device of the present invention, it is preferable that the atmosphere improving layer is a kneaded product of an atmosphere improving substance and a thermoplastic resin. According to this, when the atmosphere improving layer is a kneaded product of the atmosphere improving substance and the thermoplastic resin, the absorption rate is inferior to that of the powder, but the water resistance is improved, and the water retort such as porridge.

It is preferable to include at least one of a volatile animal repellent, an oxygen absorber and an adsorbent. According to this, according to various applications, since it is possible to adopt an atmosphere improving substance,
It can be an articulator for various purposes.

The wrapping body with an engaging device of the present invention is a wrapping device with an engaging device which is formed by welding the periphery of a sheet and blocks ventilation to the contents. The occlusion device according to any one of claims 10 to 15 is heat-welded.

Here, as the packaging bag of the package with an engaging device, a sheet having either a single-layer structure having only a base material layer or a two-layer structure having a base material layer and a sealant layer fused with the engaging device is used. It is possible to adopt a bag-shaped product.

As the material of the base material layer, PET (polyethylene terephthalate), NY (nylon), CPP (cast polypropylene) or the like can be used. As the material of the sealant layer, polyolefin is preferable as long as it is a material similar to that of the engaging device, because it is easily heat-welded. For example, LLDPE (linear low-density polyethylene), LDPE (low-density polyethylene), PP (polypropylene) ) Etc. As a method of manufacturing the sheet that forms the packaging bag, a known method such as a casting method, a melt extrusion method, or a calendar method can be used for the sheet that forms the base material layer.

In the case of producing a sheet having a two-layer structure, as described above, after forming the sheet to be the base material layer,
A layer serving as a sealant layer is laminated on a sheet serving as a base material layer by a known method such as extrusion laminating or dry laminating.

An engaging device is heat-welded to the single-layer structure sheet or the double-layer structure sheet obtained as described above by a method such as heat sealing. Specifically, for example, the obturator is heat-sealed to two rectangular sheets so that the obturator is on the inner surface of the packaging bag. At this time, the bite
The two rectangular sheets are bag-shaped by being fused to one side closer to one side and heat-sealing the other three sides. According to the present invention as described above, it is possible to obtain the same actions and effects as those described above.

Atmosphere improving layers 12C and 13C are formed in 13A on the side opposite to 0. In addition, as shown in FIG. 8B, the strip-shaped base 1 directly below the male interlocking portion 12B of the male member 12 and directly below the female interlocking portion 13B of the female member 13 is shown.
The atmosphere improving layers 12C and 13C may be formed in 3A. In addition, as shown in FIG.
Another difference is that the opening 20 side is sealed as a heat seal portion 25.

Further, as shown in FIG. 8 (c), the atmosphere improving layers 12D and 13D are formed inside the occlusal portions 12B and 13B of the male member 12 and the female member 13, respectively. It is possible to further improve the function and further prevent the contents in the occlusal package 3 from decaying.

In the packaging body 3 with an engaging device, the sheets 30, 30 are superposed, one side on the short side becomes the opening 20, and the remaining three sides become the heat sealing part 21. The seat 30 is
It has a rectangular shape in a plane and its material is NY (nylon) and L
It has a two-layer structure with LDPE (linear low-density polyethylene).

The package 3 with an engaging device is manufactured by the following procedure. First, this articulation tool 14 is co-extruded using a mold so as to have the above-described shape.
